Samco
UV Ozone Cleaners
Samco’s UV-Ozone Cleaners utilize a controlled synergistic combination of short-wavelength ultraviolet (UV) light, high-concentration ozone (O3), and stage heating to perform high-precision dry surface treatment across semiconductor, display, and electronic device manufacturing lines. Operating under ambient pressure without reactive ionic species, these systems break down molecular-level organic contaminants from silicon wafers, compound semiconductor substrates, glass, and metallic electrodes without causing physical plasma damage or electrostatic charge buildup. Designed to support both fundamental laboratory R&D and high-throughput production environments, Samco UV-Ozone Cleaners deliver highly repeatable surface activation and wettability enhancement.

Features of UV Ozone Cleaners
Samco’s UV-Ozone Cleaners integrate short-wavelength ultraviolet (UV) radiation, high-concentration ozone (O3), and substrate stage heating to achieve thorough photochemical organic removal without plasma-induced physical damage. Simultaneous exposure to 184.9 nm and 253.7 nm UV light dissociates atmospheric oxygen into ozone (O3) and atomic oxygen, while concurrently cleaving carbon-carbon molecular bonds within organic surface contaminants. Substrate stage heating accelerates these oxidation kinetics, rapidly converting organic scum, photoresist residues, and microscopic contaminants into volatile gases (CO2, H2O).
Engineered for sensitive electronic components, gate oxides, and compound semiconductor substrates, this non-plasma process operates under ambient pressure without energetic charged ions, physical sputtering, or high-voltage RF fields. By eliminating electrostatic discharge (ESD) risks and surface lattice degradation, the system safely modifies surface energy and lowers liquid contact angles across silicon, compound semiconductors, glass, and metal electrodes. This controlled photochemical surface activation optimizes surface energy prior to thin-film deposition, spin coating, or wafer bonding, delivering reproducible dry surface conditioning from university R&D laboratories to high-reliability device fabrication lines.
UV Ozone Cleaners FAQ
- How do UV light, high-concentration ozone, and stage heating interact during the cleaning process?
- The 184.9 nm UV radiation photo-dissociates atmospheric oxygen to generate high-concentration ozone (O3), while 253.7 nm UV light dissociates O3 into highly reactive atomic oxygen. Simultaneously, UV light absorption cleaves molecular bonds within surface organic contaminants. Substrate stage heating accelerates the thermal oxidation rate of these cleaved organic fragments into volatile trace gases (CO2, H2O), providing rapid organic residue removal.
- What are the primary process differences between UV-Ozone Cleaners and RF Plasma Cleaners?
- RF Plasma Cleaners utilize charged ions and energetic physical sputtering to clean and etch surfaces. In contrast, UV-Ozone Cleaners rely entirely on non-plasma photochemical oxidation under ambient pressure. This eliminates physical ion damage, surface roughening, and electrostatic discharge (ESD) risks, making UV-Ozone processing ideal for delicate thin films, gate oxides, and sensitive electronic structures.
- Which substrates and process steps benefit most from UV-Ozone surface treatment?
- UV-Ozone systems are primarily deployed to clean silicon wafers, compound semiconductor substrates (such as GaN and InP), glass plates, and metal electrodes prior to thin-film deposition, spin coating, or wafer bonding. They are also extensively utilized in academic R&D laboratories and advanced device fabrication lines where physical sputtering damage must be completely avoided.
- How does stage heating improve overall process throughput in UV-Ozone cleaning?
- Elevating substrate temperature accelerates thermal-chemical oxidation kinetics at the surface interface. This increased reaction speed reduces the exposure time required to volatilize carbon-based contaminants into CO2 and H2O, enabling faster processing cycles while preserving surface planarity.
- Can Samco UV-Ozone Cleaners handle process scaling from academic R&D to automated production?
- Yes. Samco designs UV-Ozone platforms using standardized stage geometries, uniform UV lamp arrays, and consistent ozone flow topologies. Process parameters established in university or R&D laboratories—such as UV exposure intensity, stage temperature, and cycle duration—transfer directly to batch or automated packaging and fabrication lines with minimal re-qualification.
